Available in PDF, EPUB and Kindle. Book excerpt: As CMOS technology extends to and beyond 65-nm technology node, many challenges to MOSFET were raised. The industrial and academic communities are aggressively searching for solutions to meet these challenges: (1) non-classical CMOS to extend the life of CMOS technology, and (2) fundamentally new technologies to replace CMOS technology including molecular electronics. The approach of hybrid silicon/molecular electronics is to provide a smooth transition technology by integrating molecular intrinsic scalability and diverse properties with the vast infrastructure of traditional MOS technology. The focus of this research is on integrating redox-active, organic molecules into Si-based structures to first, characterize and understand the properties of molecules; second, generate a new class of hybrid silicon/molecular devices for memory applications; and third, open a new way to develop purely molecular-scale devices. This dissertation has concentrated on the fabrication, characterization and simulation of hybrid CMOS/molecular devices for memory applications: (1) Specific procedures have been successfully developed for attaching redox-active, tightly-bonded, well-packed, molecular self-assembled monolayers on Si and SiO2 surfaces via solution-phase or vapor-phase deposition. (2) An electrolyte/molecule/Si structure has been implemented for electrical characterizations and theoretical simulations to understand the molecules and their application in memory devices, including DRAM and FLASH devices. (3) Two different strategies to achieve multibit memory have been developed and optimized using the methods of attaching mixed monolayers and stacked multilayer films. (4) Molecular multilayer films with very high surface coverage have been achieved for application in memory devices. Metal/molecule/Si sandwich structures using molecular multilayer films were fabricated and exhibited nonvolatile electrical switching properties. A set of control experiments indicate that these sw.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this dissertation is on creating electronic devices that utilize unique charge storage properties of redox-active organic molecules for memory applications. A hybrid silicon-molecular approach has been adopted to make use of the advantages of the existing silicon technology, as well as to study and exploit the interaction between the organic molecules and the bulk semiconductor. As technology heads into the nano regime, this hybrid approach may prove to be the bridge between the existing Si-only technology and a future molecule-only technology. Functionalized monolayers of redox-active molecules were formed on silicon surfaces of different doping types and densities. Electrolyte-molecule-silicon test structures were electrically characterized and studied using cyclic voltammetry and impedance spectroscopy techniques. The dependence of the oxidation and reduction processes on the silicon doping type and density were analyzed and explained using voltage balance equations and surface potentials of silicon. The role played by the silicon substrate on the operation of these memory devices was identified. Multiple bits in a single cell were achieved using either molecules exhibiting multiple stable redox states or mixed monolayer of different molecules. Self-assembled monolayers of redox-active molecules were also incorporated on varying thickness of silicon dioxide on n- and p- silicon substrates in an attempt to create non-volatile memory. The dependences of read/write/erase voltages and retention times of these devices were correlated to the SiO2 thickness by using a combination of Butler-Volmer and semiconductor theories. The region of operation of the silicon surface (accumulation, depletion or inversion) and the extent of tunneling current through the silicon dioxide were found to influence the charging and discharging of the molecules in the monolayer. Increased retention times due to the presence of SiO2 can be useful in realizing non-volatile memorie.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Redox active molecules have been studied for several years due to their interesting charge storage properties for future application in molecular memory devices with multi-bit low-voltage operation and ultimate scalability. Hybrid Si-Molecular devices with liquid electrolyte as gate contact have been demonstrated for future DRAM and FLASH memories. The focus of this dissertation work has been on developing the completely solid state hybrid Si-Molecular devices embedded with redox active molecules to facilitate ease of integration. In addition, redox active molecules have also been explored in potential application in organic photovoltaic cells. This work exploits the charge storage properties of redox molecules in solid state devices and the absorption profile of the redox polymers. The charge transfer and charge screening process in conventional electrochemical cell with liquid electrolyte has been characterized using cyclic voltammetry measurements. The role of the liquid electrolyte and the electrical double layer in electrochemical cell for the redox process has been discussed. The solid state approach to hybrid Si-Molecular devices has been proposed. The solid state dielectric layer has been considered to replace electrical double layer. The requirements of dielectric layer and deposition methods in solid state molecular memory device are investigated for preservation and characterization of the redox molecules. AlN, Al2O3 and HfO2 are deposited and examined on top of redox active polymers or redox monolayer in metal-insulator-molecules-silicon (MIMS) or metal-insulator-molecules-metal (MIMM) capacitors. The CyV measurements indicate that the redox properties are preserved after dielectric layer deposition on molecules. The leakage of MIMM capacitors has been greatly improved after the optimization on HfO2 atomic layer deposition conditions and the W/WN gate stack. The low leakage current of MIMM structure provide a reliable test platform for redox molecules as.
